The seller is OK. You get some extras with the deal. The vape is a cheap, made in China box with no warranty. The digital display won't show you the true vaping temp, and just makes a breakdown much more likely. I also wouldn't trust these cheap boxes as far as safety of design and construction parts. IMO you can't get a decent, safe vape below $100, unless you go with a butane powered VaporGenie.

If you want a quality, safe box vape that'll last, look for the Vaporwarez/Vapor Warez Vaporcannon on eBay. You get a 5 yr. warranty, aluminum grinder, scale, and extra screens for $120. For $20 more you get hands free, but at that price I'd rather get the Da Buddha (dabuddhavaporizer.com). With 'paul' as a coupon code, you get 10% off and a very high quality vape.
